Abstract:
An inductive sensor device has a scale with scale elements that provide a field pattern in at least one line extending in a measuring direction. The inductive sensor device contains at least one receive circuit with at least one receive coil. The receive coil and the scale are moveable relative to each other in the measuring direction. The receive coil extends from a first end to a second end in the measuring direction. It has a first end section directly adjacent to the first end and a second end section directly adjacent to the second end, and middle section. Each of the sections contains at least one loop of the receive coil. In the end sections the loop area decreases from loop to loop from the loop next to the middle section toward the respective end. Such a loop design compensates for misalignments between the receive coil and the scale.
